Peru was a founding member of the League of Nations, starting on January 10, 1920. In 1932, a civilian takeover of the city of Leticia soon became an undeclared war between Peru and Colombia as the Peruvian Army moved to oppose a Colombian re-occupation.[5] After months of diplomatic negotiations, the governments accepted mediation by the League of Nations, and their representatives presented their cases before the council. A provisional peace agreement, signed by both parties in May 1933, provided for the League to assume control of the disputed territory while bilateral negotiations proceeded.[6] In May 1934, a final peace agreement was signed, resulting in the return of Leticia to Colombia, a formal apology from Peru for the 1932 invasion, demilitarisation of the area around Leticia, free navigation on the Amazon and Putumayo Rivers, and a pledge of non-aggression.[7]
During World War II, Peru joined the Allied forces in 1945 and joined the UN as a founding member in the same year.[1]
Peru has been a non-permanent member of the United Nations Security Council from 1955 to 1956, 1973 to 1974, 1984 to 1985, 2006 to 2007, and, most recently, from 2018 to 2019.[8]
Peacekeeping
Peru, as a founding member of the UN, has had a high level of participation in peacekeeping missions, collaborating with troops commonly known as the "Blue Helmets". In 1988, during the management of the Peruvian Javier Pérez de Cuéllar as Secretary General of the UN, the United Nations peacekeepers received the Nobel Peace Prize.
Peru has sent troops from the Army, the Navy, and the Air Force. The missions in which the country has participated (and, as of 2023, continues to participate) are:[3][9]
